N40-N51: Diseases of male genital organs
N43: Hydrocele and spermatocele
The conditions hydrocele and spermatocele, grouped under ICD-10 code N43, refer to disorders related to fluid accumulation in the scrotum. A hydrocele is a condition where fluid accumulates in the sheath surrounding a testicle, causing the scrotum to swell. It may occur due to inflammation or injury in the scrotum or from the natural flow imbalance of fluid secretion and absorption. On the other hand, a spermatocele is a cyst that develops in the epididymis, the small, coiled tube located on the upper testicle that collects and transports sperm, and is filled with sperm and fluid. These conditions typically present as a painless enlargement of the scrotum and are often discovered during a physical examination. Both conditions typically do not affect fertility, but if they become significantly large or cause discomfort, they may require intervention.
